A Mumbai-based payments company wants to define the maximum amount of data loss, measured in time, that it can tolerate after a system failure. Which term describes this measure?
The Recovery Point Objective (RPO) is correct. It states how much data, measured as time back from the failure, an organisation can afford to lose. It decides backup or replication frequency. RTO instead measures how quickly service must be restored.
- ARecovery Time Objective (RTO)
- BRecovery Point Objective (RPO)Correct
- CMaximum Tolerable Outage (MTO)
- DMean Time Between Failures (MTBF)
Explanation
RPO expresses the point in time to which data must be restored, so it measures tolerable data loss in time. RTO is the target time to restore service, which is a different idea. MTBF is a reliability measure of how long a component runs between failures.
Did you get it right without looking?
One question tells you little. A timed set on Information Systems shows your real accuracy, how long you take and where you lose marks.
